Phil Harrison may have left Sony in February, but GameSpot reported that he may have left some parting gifts as he filed two patents last January that could be potentially used for games.
One of the patent is a "handheld device with touchscreen and digital tactile pixels" that differentiates itself from similar existing technologies. How? The patent states, "existing touch screens are configured to receive a mechanical input and provide a visible output," but they "are not configured to provide both a visible and a mechanical output." Basically, it's a multi-point touchscreen and feedback technology that tells you, "Yes man, you're touching the screen," not just through visuals but through other means.
The other patent filed by Harrison is another handheld device that is capable of transfering images through another device by specific gestures. So we might be able to literally "pass" some information around by mocking a card toss. Once the image has been received, it will appear on both devices.
Both of these patents were only made public a couple weeks ago and they can be utilized in multiple applications including "gaming device, phone, portable media player, email device, web browser device, or navigation device." Did it mention gaming device? Oh yes it did. Now to ponder on the endless possibilities...
